Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552194, here are decompositions:

67 + 31552127 = 31552194
137 + 31552057 = 31552194
197 + 31551997 = 31552194
257 + 31551937 = 31552194
293 + 31551901 = 31552194
337 + 31551857 = 31552194
367 + 31551827 = 31552194
461 + 31551733 = 31552194

Showing the first eight; more decompositions exist.
